Question

Leo and Alex, with masses of 100 kg and 50 kg, are holding opposite ends of a rope. They are standing on the middle of a frozen lake, where friction is negligible. They are standing 6m apart. Leo gives the rope a pull – 100 N – for one second. Let’s call the start of this pull t=0. a) What is their subsequent motion? On a position-vs-time graph, plot the position of both of them over time. b) Do they move towards or away from each other? If it is towards, when and where do they meet?
